Abstract
A lumbar support system includes a fixed mounting bracket having a first traction cable sleeve support, a second sleeve support and a slider guide. A traction cable having a wire disposed to slide axially through a first sleeve and second sleeve, is attached to the first sleeve support of the fixed mounting bracket and to an actuator operatively engaged with the traction cable wire. A slider is also attached to the traction cable wire, is operatively engaged with the slider guide and adjusts the position of a flexible support element as it slides along the slider guide.
Claims13
An adjustable lumbar support device comprising:
- a fixed mounting bracket having a first sleeve support, a second sleeve support and a slider guide;
- a slider engaged with said slider guide, said slider being attached to a support element such that movement of said slider moves said support element;
- and
- a first traction cable and a second traction cable, each being engaged with an actuator and each having a wire disposed to slide axially through a sleeve, said first traction cable having a first wire end attached to said slider and said first traction cable having a first sleeve end attached to said first sleeve support and said second traction cable having a second wire end attached to said slider, and said second traction cable having a second sleeve end attached to said second sleeve support;
- whereby traction on said first traction cable draws said slider and said support element in a first direction and traction on said second traction cable draws said slider and said support element in a second direction.
An adjustable lumbar support device comprising:
- a guide rod adaptable to mount on a seat frame;
- a flexible support element mounted to slide on said guide rod;
- a fixed mounting bracket mounted on said guide rod, said fixed mounting bracket having a first sleeve support, a second sleeve support, and a slider guide;
- a slider engaged with said slider guide, said slider having a third sleeve support and said slider being attached to said flexible support element such that movement of said slider moves said flexible support element;
- a first traction cable and a second traction cable, each being engaged with an actuator and each having a wire disposed to slide axially through a sleeve, said first traction cable having a first wire end attached to said slider and said first traction cable having a first sleeve end attached to said first sleeve support and said second traction cable having a second wire end attached to said slider, and said second traction cable having a second sleeve end attached to said second sleeve support;
- whereby traction on said first traction cable draws said slider and said flexible support element in a first direction and traction on said second traction cable draws said slider and said flexible support element in a second direction;
- and
- a third traction cable engaged with a second actuator and having a third wire end disposed to slide axially from a third sleeve end, said third sleeve end being attached to said third sleeve support on said slider and said third wire end being attached to said flexible support element;
- whereby traction on said third traction cable flexes said flexible support element into a selectable degree of lumbar supporting arch, said selectable degree of lumbar supporting arch being maintained upon movement of said flexible support element in said first direction and in said second direction.
A method of assembling an adjustable lumbar support, comprising the steps of:
- mounting a slider on a slide guide, said slide guide being on a fixed mounting bracket;
- attaching said slider to a support element;
- attaching a traction cable to said adjustable lumbar support by attaching a traction cable sleeve end to said fixed mounting bracket and attaching a traction cable wire end to said slider such that traction on said traction cable moves said support element.
A variable ergonomic support device comprising:
- a support assembly mountable on a seat frame;
- means for slidably mounting a pressure element on said support assembly;
- means for engaging a first traction cable with said support assembly and said pressure element such that traction on said first traction cable moves said pressure element in a first direction;
- and
- means for engaging a second traction cable with said support assembly and said pressure element such that traction on said second traction cable moves said pressure element in a second direction substantially parallel and opposite said first direction.
